S Fork Lk TH and NW slopes route up Lackawanna. Then over to Casco and on to French via Frasco BM. Descent into basin to E of Casco-Frasco Col from about half way down to col from Frasco BM (loose red gravel; perfect for descending), and back down to TH. A wonderful ridge-y loop. Nothing beyond 2+.

1/19/14 - Via Echo Canyon. A wind scoured line provided an avy safe path to the Bull Hill/Casco saddle and we ran the ridge over Casco and then out and back to French (over Frasco both ways). Quite a long day in winter and the ridge was more interesting than I remembered.
